FIELD: information technology. ^ SUBSTANCE: concurrency control between multiple data transactions involving the same data includes steps for comparing the version identifications which uniquely identify versions of the data during a read request and during a write request of a data transaction. An exception is thrown if the version identifications do not match, and the exception is handled within the data transaction. ^ EFFECT: high reliability of processing data during concurrent data processing. ^ 20 cl, 9 dwg, 1 tbl |
